>>Displaying the Nth line翻譯社This example prints three. 
Note that instead of using the more command's /e switch, the skip option could have been used with the for /f command, however, this fails is it is set to any number less than one. 
顯示第n行翻譯社列印第三行. 
注意啟用more號令的擴展功能(/e)開關,同時,ship選項曩昔經常使用於for /f命名中,然則當設定的數量小於現實值時,將導致失敗
